You can get the latest postfix (including > postscreen) for CentOS 6 from GhettoForge (www.ghettoforge.org). Thanks for your help and so quickly :) I decided to try with current version of postgrey from projects github repository. https://github.com/schweikert/postgrey/releases/tag/version-1.36 as I want to avoid using more 3rd party repos. Doing the first steps in manual installation (create directory and user) I found out, that I lack from knowledge on "ls" output.. There is a difference that I don't understand. What does the "." at the right side of the attributes list mean? directory manually created on the shell: drwxr-x--x 2 postgrey postfix 4096 Apr 22 17:19 /var/spool/postfix/postgrey/ created by package installation: drwxr-x--x. 2 postgrey postfix 4096 Apr 13 16:23 /var/spool/postfix/postgrey I used this commands to create the first one # mkdir /var/spool/postfix/postgrey # chmod 751 /var/spool/postfix/postgrey # groupadd --gid 493 postgrey # useradd --system --gid 493 --uid 493 --home /var/spool/postfix/postgrey -M --shell /sbin/nologin postgrey # chown postgrey /var/spool/postfix/postgrey # chgrp postfix /var/spool/postfix/postgrey Can you give explanation what is causing the difference compared to the package created directory?
